Technique of Magnetic Separation. Each mineral is separated based on its magnetic susceptibility. Ferromagnetic minerals - The poles of a magnet are wrapped in paper and passed over the mineral mixture. Ferromagnetic minerals will stick to the magnets and, thus, get separated from the ore mixture. Paramagnetic minerals – These are weakly
